Which selection criteria to take into account?

In order to make the right selection, the operating conditions of the compressor should be known very well. Temperature, air quality and humidity play an important role in the selection of the right oil.

Temperature

The most important parameter is temperature.
First condition to decide on, is based on the element outlet temperature or ambient temperature. Both are expressed in different ranges. If possible, selection should be done based on element outlet temperature. Where element outlet temperature is not available, ambient temperature gives a good indication

Air quality

Second condition to decide on, is dust contamination or air quality in the compressor room. As an example: a cement factory can be seen as a dusty environment compared to an automotive company which is expected to be a clean environment. In certain countries, the average dust levels can also be higher than the average standard. It needs to be assessed on a case by case basis

Humidity

Last condition to be decided on is the humidity, where countries with a tropical rainforest or monsoon climate are seen as humid countries. Also depending on the compressor room conditions, the intake air can have a high humidity level

Temperature	Humid	Dust	Type
Element outlet < 95°C (203°F) or Ambient < 30°C (86°F)	N	N	Mild
	Y	N	Mild
	N	Y	Mild
	Y	Y	Demanding
95°C (203°F) < Element outlet < 105°C (221°F)or 30°C (86°F) < Ambient < 40°C (104°F)	N	N	Demanding
	Y	N	Demanding
	N	Y	Demanding
	Y	Y	Extreme
Element Outlet > 105°C (221°F) or Ambient > 40°C (104°F)	–	–	Extreme

The most important parameters influencing the oil life time and performance characteristics are ambient temperature, dust or air quality and humidity. These parameters are described as the ambient conditions, and allow you to classify your application into mild, demanding or extreme.
